We are also coming up on a 1,200 mile road trip and by then it should be time to change the oil. Our consumption seems to have slowed down from 1qt/2,500 miles to about 10oz/2,500miles (holding steady at 3/4 full). Hoping to not add any on this trip so I can send in a sample for testing. Along with gas/moisture results, the TBN should be really high on Pennzoil Platinum with only a 5K run …I was thinking about how we have a lot of road trips coming up in the next 30 days, at least 4000 miles worth, and I was on the fence about going for an oil change while it was nice out and I had the time. It would be interesting sometime to send off a sample at an oil change and have it tested to see how much gas/moisture contamination is there.
